Vilrriasrnuch `as device is arranged pivoted to the generalwgbase, the opening thereof aswell as V'the'-pres''entatioigiof 4the cards within reach rof 'the userjs hand Vr sight,fwill depend on the .dis-j placement of; said device.

" vSince the `operation of thevdevice depends "on the 'position of 'the'door or cover of the box or cavity, the mount may be used for locating card boxes in cabinets, desks, bookcases and other pieces'of furniture, as well as embedded lin walls or the like.

In order that the invention may be more clearly understood and readily carried into practice, same has been illustrated by way of example and in some preferred embodiments in the accompanying drawings, wherein: l

Figure 1 is a perspective view of the card index box in idle position, viz; within-the cavity therefor, the upper portion of the casing being broken away so as to show the mount which is the subject of the present invention.

Figure 2 is a perspective View of the card-box 'in operative position, showing the manner in which it remains extended partially out of the furniture, for ready consultation of the contents thereof.

Figure 3 is a plan view of the card tbox in inoperative position, showing the arrangement of the holder pivot relative to the rotor shaft of said card box, v

Figure 4 is a cross-section taken on line N-N of Fig, 3.

Figure is the same plan view of Figure 3, but with the card 'box in operative position, showing the manner in which, upon -opening the cover constituting the holder, the rotary body of the card box is displaced towards the front, extending partially out of the cavity so as to remain within reach of theoperator.

Figure 6 is a side view of another form of card box mount, shown in inoperative position. This form, based on the same principle, diifers from that of the previous figures only as regards the positions of the shaft and rotation pivot, which inthe.preserit instance are in horizontal posiy tion, so thatV the displacement of the cover is effected on' a verticalplane and [Figure ,'7 is a., side View roi the same form of Figure, `shows 'the ,card b ox in operative position." A'

,Y Thesame reference characters indicate like or ,corresponding parts or' elements throughout the diierent figures." j `As may-be seen from the drawings, a isa cavity and, as stated above, said cavity may form part of a simple vcabinet, or of a desk or other piece of furnitureto which it is desired to apply Said card 110K.-y i

Said cavity aisA closed by means of a cover or door b, which in the presentinstance is a corner door and comprises the angle and part ofthe two walls ofthe piece of furniture whereinf'said cavity isfornned.

Saidlcover or doorb includes front walls I vandupper and lower walls 2 and' 3, respectively,

forming a casing with said front Walls l, as clearly shown in the drawings.

The upper and lower portions of the casing of cover b are each provided with a pivot 4 through which said casing is mounted on at bars 5 secured at their ends to the upper and lower walls of said cavtiy a. Under these conditions, the casing formed b said cover b is mounted in a pivoting manner and therefore, when taken =by the handle 6 thereof, is capable of :being displaced from the position shown in Figs. 1, 3 and 6, to that shown in Figures 2, 4 and 7.

' At a certain distance from the axis of said pivots 4 and parallel thereto, a shaft 1 is mounted between the walls 2 and 3 of the casing formed by the cover/ or door b, and as may be seen in Figure 5, on said shaft 1 is arranged a rotor c in the form of a shelf provided with a central drum to which cards 8 or other recording elements are attached.

Since the card index rotor c is mounted on said cover b by means of the shaft 1 located at a r` certain distance from the axis of the pivots 4, upon the latter being opened it will so displace said rotor c that it will be suicient to open or close said cover b to obtain the operative and inoperative position, respectively, of said card index.

The assembly isvso calculated that when the cover b is in closed position as shown in Figures l, 3 and 6, the rotary card index will remain completely housed in the cavity a acting as a shielded housing.

dex c will extend out ofthe cavity in its opera,-`y

tive position, will depend on the spacing between shaft 'I and the axis of pivots 4.

said shaft 1 will be located rearwardly of the axis of pivots 4, and therefore upon opening the `As shown in` Figures 1, 3 and 6, when in inoperative position' its inoperative position, shielded bythe same cover as shown in Figures 2, 4 and '7, the path followed by shaft 'I'is such that it will remain in front of said pivot axis.

In the form of construction of Figures l, 2, 3,

4 and 5, said axis of pivots 4 of cover b and said A rotor shaft 1 mounted on said cover are vertical, and consequently both the cover bI and the rotor c act on a horizontal plane of displacement and rotation.

On the other hand, in the form of construction of Figures 6 and 7, the axis of pivots 4 and shaft 'I are located horizontally, so that the cover or door b and the rotor c are displaceable and rotatable on avertical plane.

It should be understood that apart from being arranged vertically or horizontally, the shafts and pivots may be `arranged obliquely, according to the position in which the body of the card index c should work. l

In short, the invention comprises a cavityv a closed by means of a box-shaped cover` or door b mounted by means of pivots 4 on the' Walls of said cavity, and in turn `said cover serves as a 'mount for a rotary card index c the shaft 'I of which is located at a certain distance beyond the axis of said pivots 4, so that when said card index is within the cavity a and clo'sed by said cover b, 40

the opening `of the latter will cause a displacement of the card box whereby part of the cards 8 will be moved out of the cavity and within reach of the used, all without losing the mounting on the box of said cover bl, where the card index will remain inI a floating-like manner. In the same easy manner, upon closing the cover b, the card index will return into the cavity and assume coverr b.

Furthermore, it is evident that several modifications in construction and detail may be made by those skilled in the art, without departing from the scope of the invention as clearly set forth in the appended claims.

What vis claimed is: 1. A mountfor rotary card index systems, comprising a housing provided with a door opening, a door adapted to closesaid opening and including two parallel wings spaced from each other and projecting into said housing when said door is closed, said door being pivoted to said housing onv an axis normal to and intersecting said Wings at a sufficient distance from said opening to permit at least a major portion of saidy door to be revolved completely into said housing, and a card supporting rotor mounted between said wings of said door for rotation about an axis disposed parallel toand inwardly of the pivot axis of said door whenithe latter is closed, whereby the rotor is caused lto project from said opening when said door is revolved into the housing.

2. A mount for Arotary card index systems, as claimed in claim 1, in which said door has two front Walls at right angles to each other forming in-closed position of the door `a corner of said housing, said front walls and wings of said door constituting a substantially triangular box intersected by the rotor axis near the center of the triangle base.
